My invention relates to a casing, receptacle, container or the likehereinafter generically termed a casing and adapted to con tainasuitable substance or material, as fuel which may be semiflsolid,jelly-like or of viscous consistency. 1 Y

My invention relates to a casing, as aforesaid, having a nozzle of novelcharacteristics adapting it for readily detachable association with apyrophoric lighter casing.

Further advantages, objects and characteristics of my invention willbecome apparentfrom the following detailed description takenin'connection with the accompanying 1 drawings.

vMy invention resides in the casing, nozzle features, and in thecombination of parts and features of construction of the characterhereinafter described and claimed.

This application is a division of my application Serial N 0. 392,426,filed September 13, 1929. a

For an understanding of my invention, reference is to be had to theaccompanying drawings, in which:

F'gure l is' an elevational view of a fuelcontaining casing asconstructed in accordance with my invention;

Figure 4 is an elevational View, partly.

' broken away, and shows the fuel-containing casing after a quantity offuel has been removed therefrom.

\ For purposes of explanation and to illustrate an important applicationof my invention, I have shown on the accompanyingdrawings an arrangementfor introducing semi-solid or jelly-like fuel interiorly of the casingof pyrophoric lighting mechanism L which may be .of any suitable ordesired character or type. As illustrative of one of the many forms oflighting mechanism to which my invention is applicable, I have shown theaforesaid lighting-mechanism L as comprising a casing '1 having 2 and abottom wall 3. Projecting from the top casing wall 2 is theflameroducing mechanism per se which may be 0 any suitable type. Asshown such mechanism comprises a member 4 reciprocatory, by manualaction, to swing a lever 5 on a shaft or memher 6 carried by spacedstandards projecting from said top casrn wall. The lever 5 carries theusual snu er cap which forms a, movable housing for the end of a wicktube 7 extending through the top wall of the casing 1. As is usual, awick 8 disposed interior- 1 of said casing 1 extends through the wicktube 7 and projects slightly therebeyond.

a top wall When the member 4 is moved toward the top casing-wall 2,suitable spark-producing memhere, not shown, co-act to produce a showerof sparks which are directed toward the end of wick 8, the latter beingexposed at this time due to movement therefrom of the aforesaid snuffercap in response to pivotal movement of lever 5 as effected by the lastdescribed movement of member 4. 7

As is usual in the art, thecasing 1 constitutes a reservoir orreceptacle for fuel which heretofore, usually, character, as benzine,gasoline, or the like. For introducing such fuel into the casing 1, ithas been customary to. provide an opening or perforation 9 in the bottomcasing wall 3, said opening being constituted by a sleeve-likeextension, if desired, and being interiorly threaded for engagement withthe exterior threads of a closure cap or plug 10. When the cap 10 isremoved, a supply of fuel may be introduced into the casing 1 which mayor may not, as desired, contain a body of suitable material forabsorbing the fuel.

In lieu of the aforesaid liquid fuel and in accordance with myinvention, there is utilized and introduced into the casing 1, or anyother similar or desired casing, semisolid or jelly-like fuel of anysuitable character' such, for example, as described in the co-pendingapplication of Nathan Proper, Serial No. 342,306, filed February 23,1929.

Semi-solid or jelly-like fuel of the character described above may bedispensed or has been liquid in sold on the market ina casin or tube Twhich, in the example illustrate comprises a fuel containin section orbody portion the wall structure 0 which is deformable sheetlike metallicmaterial closed or sealed at one end and, at the other end, comprising asleeve-like extension or spout a servin as a nozzle or orifice having anopening 0 suitable extent for the passage therethrough of the semi-solidor jelly-like fuel upon application of pressure to said wall structure.

In accordance with my invention, the extension or spout a is of conicalconfiguration converging in a direction leading from the body section oftube T and is formed of suitable impressionable material, as soft metal,and, throughout a great or the major length thereof, comprises asubstantially smooth or even exterior surface. Immediately adjacent theend of said spout or nozzle a, suitable threads 5 may be provided forthe rece tion of a closure cap 0.

ith the closure cap a threaded to the nozzle a, the fuel-containing tubeT is dis-.

nsed or sold on the market in the condition illustrated in Figure 1.When the purchaser of such a tube T desires to refill or restock thecasing of his lighting mechanism with fuel, the closure cap 10 of thelatter is removed and the closure cap 0 of the tube T is likewiseremoved. Thereupon, the nozzle a of tube T may be inserted into thefilling opening of the lighter casing and by suitably applied pressureaxially of said tube T, while simultaneously rotatin the same, one ormore threads (1 are forme on the spout a by die-like action of theinterior threads 0 the opening (2 whereby the tube T is so held inassembled relation to thecasing of the pyrophoric lighting mechanismthat ressure upon the wall structure of said tu e T forces fuel throughthe nozzle (1 into the lighting mechanism casing to charge the latterwith a supply of fuel F, Figure 4.

After a suitable supply of fuel has been introduced into said last namedcasing, the tube T, by reverse rotation, may be unthreaded therefromwhereupon the respec-- tive closure caps may be placed in position, thecap 10 being threaded into the lighting mechanism casing and the closurecap 0 'ing threaded to the threads I). of spout a.

The tube T may now be'laid away until it is again desired to refuel thelighting mechanism whereupon the operation described above may berepeated, the previously formed threads (1 again serving to unite thetwo casings.

As herembefore stated, the spout a, preferably, has an exterior conicalconfiguration and it is desirable that the inclination of the coneelements be relatively sharply inclined with respect to the cone axis.This arrangement is preferable because the spout a is thereby adapted tobe associated with any i b such changes and modifications.

desired to be one of a pluralit of easing filling openings, even thou hsuc fillin openings may have substantia y different iameters, as thoseof different makes, models or styles, those of lar r diameter,obviously, co-acting with an threading the spout a nearer the base ofthe cone and those of smaller diameter co-acting with and threading saidspout a somewhat nearer the apex of the cone.

An added advantage of my invention resides in the fact that a singlespout a may be adapted to be associated with a plurality of li htercasings even though the fuel openin s thereof have different diameters.This folows because the fuel opening of a certain diameter causes theformation of threads in one region along the spout a, and the fillingopening of another diameter causes the formation of other threads inanother region therealong.

By the above described manner of assembling the casin s T and L, a tightjoint is obtained and, t erefore, leakage or wastage of fuel is obviatedwhen transfer is effected from one casing to the other. The fuel comesinto the casing L under pressure, the displaced air passin to theatmosphere by way of the wick tu e 7 To some extent, this action resultsin the transfer of fuel to the immediate vicinity of the wick 8 whichabsorbs the fuel in the lighter mechanism casing and causes the transferof inflammable material to the region of combustion.

Although illustrated particularly in connection with the refueling ofthe casings of lighting mechanism, it shall be understood f that myinvention is useful in other relations for effecting the transfer ofmaterial other than fuel in either direction from one casing to anotherwhen they are connected in accordance with my invention.

While the invention has been described with respect to a certainparticular preferred exam le which gives satisfactory results, it will eunderstood by those skilled in the art after understanding theinvention, that various changes and modifications may be made withoutdeparting from the spirit and scope of the invention and it is intendedtherefore in the appended claim to cover all What is claimed as new andsecured by Letters Patent is:

A casing having a body section and a nozzle, threads on said nozzle fora closure cap, said nozzle adjacent the tip thereof comprising anunthreaded conical section of soft metal adapted to be externallythreaded by the die-like action of the internally threaded fillingopening of a pyrophoric lighter casing.

In testimony whereof I have signed my name to this specification.

LOUIS V. ARONSON.
